Avery has a few things (okay more than a few) confused. However, her logic is so much better than conventional logic that I can't even explain it to her without confusing myself a little. So, in order to make things simple, I'm just going to try to change the thinking of the world and allow Avery's logic to remain. I'm pretty sure I'll be more successful that way.
Consider yourself warned:
The thing cowboys ride on are cows, not horses.
Unicorns don't have horns on their head, they have corns.
If you could, please spread the word.
